getStepData

Get a new instance of the appropriate data class.
This data class implements the StepDataInterface.
It basically contains the persisting data that needs to live on, even if a worker thread is terminated.

exportResources

Since the exported transformation that runs this will reside in a ZIP file, we can't reference files relatively.
So what this does is turn the name of files into absolute paths OR it simply includes the resource in the ZIP file.
For now, we'll simply turn it into an absolute path and pray that the file is on a shared drive or something like that.
